Small world changes fast

The world is so small. When I walked out of the apartment, I met Amy at the street. After greeting to each other, I just realized that I haven't known where she came from yet. To my surprise, that she was from the same department which I was in my college years. And she was in the same class with daybreak. The world is so small.

And the world changes fast though. From Amy, I got to know that happybj got a child already. Congratulations to him.
